We knew the ancient Chinese were way into herb administration, but we had no idea they were into weed until some scientists found the world's oldest marijuana stash in a 2,700-year-old grave in the Gobi desert. Still-green, according to this boring report, it was found along with some super valuable and weird shit, including an earthenware pot, a horse lash and bridle or halter, a leather medicine bag, archery equipment, a rare harp, a wooden wimble tool, leather make-up bag, leather ring, and a wooden implement. Oh, and a white man's head in a basket.
